FIELD OF THE INVENTION

The present invention relates to a compound having a silsesquioxane skeleton, a polymer obtained using the compound, and uses of the polymer.

BACKGROUND OF THE INVENTION

Polyorganosiloxane has excellent heat resistance, weatherability and surface-modifying function, and therefore it is used for semiconductor insulating protective films, flame retardants and coating material additives. For example, a coating agent prepared by blending an organic polymer with polyorganosiloxane can provide the surface of a material coated with the agent with functions such as water repellency. The representative examples of the organic polymer are acryl resins, polyurethanes and alkid resins. In general, however, these polymers do not have a good compatibility with polyorganosiloxane. Accordingly, there have been the problems that the coating agent is liable to become cloudy by blending polyorganosiloxane, and that a coating film obtained from the coating agent is liable to be whitened. That is, an addition amount of polyorganosiloxane has been restricted.

It has so far been known that an introduction of a polysiloxane structure into principal chain and/or side chain of an organic polymer makes it possible to improve the characteristics of the polymer such as heat resistance, water repellency and weatherability. Disclosed in, for example, the patent document 1 is a process in which a polysiloxane-containing polymer is radically copolymerized with other addition-polymerizable monomers to thereby produce a polysiloxane graft copolymer having a polysiloxane structure in a side chain. Polysilsesquioxane having a structure in which 1.5 oxygen atom is bonded to one silicon atom is disclosed in the patent document 2. It is described in the document that a polysilsesquioxane derivative having a polymerizable unsaturated bond and two or more functional groups such as hydroxyl group and alkoxy group is copolymerized with other addition-polymerizable monomers to thereby obtain a vinyl polymer into which a siloxane side chain is introduced. All of them are considered to be excellent in heat resistance, water repellency and weatherability as compared with the homopolymers of the other addition-polymerizable monomers.

It has so far been tried to enhance the content of a polyorganosiloxane structure in an organic polymer for the purpose of improving the characteristics as described above. However, in the foregoing organic polymer having a polyorganosiloxane structure, such a high improving effect as expected has not been provided to the characteristics such as heat resistance, water repellency, weatherability and electric insulating property. Accordingly, strongly desired is a polyorganosiloxane having a structure which further elevates characteristics such as heat resistance, water repellency and weatherability in the organic polymer.

An object of the present invention is to provide a useful polysilsesquioxane derivative in order to solve the problems described above, and another object is to provide a novel polymer obtained by using the derivative. Still another object is to provide a coating agent, a plastic substrate and an optical material each obtained by using the polymer.

SUMMARY OF THE INVENTION

First, terms and codes used in the present invention shall be explained. The term “optional” shows that not only the position but also the number are optional. For example, when “optional —CH₂— in alkyl may be replaced by —O— or —CH═CH—” is expressed, plural —CH₂— may be replaced by different groups respectively. Examples in such case are alkyl, alkoxy, alkoxyalkyl, alkoxyalkenyl and alkenyloxyalkyl. Alkyl and alkylene are used as groups including both of linear group and branched group unless otherwise described. The examples of halogen are fluorine, chlorine and bromine.

The compound (1) and the polymer (3) are characterized by that they are physically and chemically stable very much on conditions usually used and that they have a good compatibility with other polymers and compounds. Suited selection of rings, bonding groups or side chains constituting the compound (1) makes it possible to suitably select the structure of the polymer (3), and therefore capable of being produced is the polymer having optimum transparency, refractive index, mechanical strength, coating property, solubility, crystallinity, shrink property, water permeability, water absorbency, gas permeability, melting point, glass transition point, heat resistance, thermal expansion coefficient, water repellency, electrical insulating property, compatibility and chemical resistance.

The compound (1), the polymer (3) or the composition containing them can be molded into a thin film, a multilayer membrane, a film, a fiber, a powder, a paste and other molded articles by a method which is usually used for producing conventional molded articles of high molecular materials. In this case, capable of being blended, if necessary, are aliphatic polyols such as ethylene glycol and propylene glycol, aliphatic or aromatic carboxylic acid compounds, carbon dioxide gas-preventing agents such as phenol compounds, flexibility-providing agents such as polyalkylene glycols, antioxidants, plasticizers, lubricants, coupling agents such as silanes, surface treating agents for inorganic fillers, flame retardants, antistatic agents, colorants, leveling agents, ion trapping agents, slid-improving agents, various rubbers, impact-improving agents such as organic polymer beads, swing-providing agents, surfactants, surface tension-reducing agents, defoaming agents, precipitation preventives, light scattering agents, UV absorbers, heat stabilizers, antioxidants, mold releasing agents, fluorescent agents, conductive fillers, foaming agents and additives such as pigments.

For example, the polymer (3) of the present invention is dissolved homogeneously in a solvent, and the resulting solution is cast on a substrate and heated to volatilize the solvent, whereby a uniform film of 1 to 100 μm can be obtained. A polymer film, a glass plate, a silicon rubber plate and a metal plate can be given as the substrate used for molding a film by the above casting method. When a substrate having a prescribed thickness is obtained, the polymer is repeatedly cast and laminated so that the targeted film thickness is obtained, and then it is heated to volatilize the solvent, whereby the substrate having a prescribed thickness can be prepared. In this case, pressing can be carried out as well while heating and applying pressure.

Further, a multilayer substrate can be obtained by laminating a metal conductive layer of gold, copper or aluminum between the films and/or on the outermost layer. Also in this case, a metal conductive film is superposed thereon and heated in the same manner as described above to volatilize the solvent, whereby the substrate having a good adhesive property with the metal conductive film can be obtained. The metal conductive layer is obtained by forming a circuit by etching. Further, it can be formed as well by a vacuum deposition method and a screen printing method.

In the tables described above, Q²-1-1 to Q²-89-2 described in the column of Q² have meanings shown in the following Formula (Q²-1-1) to Formula (Q²-89-2). A code “<” shown at a left end in these formulas shows a bonding point to an Si atom.

Comparative Example 1

<Production 1 of Polyamic Acid>

An NMP (45 g) solution of 4,4′-diaminodiphenyl ether (2.39 g) was cooled under nitrogen atmosphere. Pyromellitic dianhydride (2.61 g) was added to the above solution while maintaining the temperature of the reaction system in a range of 5 to 70° C. Then, the solution was stirred for 20 hours to obtain a polyamic acid vanish (50 g) having a polymer concentration of 10% by weight. Polyamic acid contained in the above vanish is named PA acid 1.

Example 7

<Production 2 of Polyamic Acid>

A polyamic acid vanish (15 g) having a polymer concentration of 20% by weight was obtained in the same manner as in Comparative Example 1, except that pyromellitic dianhydride was changed to Compound (1-1-4) (1.49 g) and 4,4′-diaminodiphenyl ether was changed to Compound (1-3-7) (1.51 g) and that a use amount of NMP was changed to 12 g. Polyamic acid contained in the above vanish is named PA acid 2.

Example 8

<Production 3 of Polyamic Acid>

A polyamic acid vanish (15 g) having a polymer concentration of 20% by weight was obtained in the same manner as in Example 5, except that Compound (1-1-4) was changed to pyromellitic dianhydride (0.39 g) and that a use amount of Compound (1-3-7) was changed to 2.61 g. Polyamic acid contained in the above vanish is named PA acid 3.

Example 9

<Production 4 of Polyamic Acid>

A polyamic acid vanish (10 g) having a polymer concentration of 30% by weight was obtained in the same manner as in Example 5, except that a use amount of Compound (1-1-4) was changed to 2.63 g and Compound (1-3-7) was changed to 4,4′-diaminodiphenyl ether (0.38 g) and that a use amount of NMP was changed to 7 g. Polyamic acid contained in the above vanish is named PA acid 4.

Example 10

The respective vanishes of PA acid 1 to PA acid 4 were diluted to suitable concentrations by butyl cellosolve and coated on a glass substrate by means of a spinner. It was pre-baked at 80° C. for about 5 minutes and then subjected to heat treatment at 220° C. for 30 minutes and then at 300° C. for 60 minutes to form the respective polyimide thin films. These polyimide thin films are designated as PI-1, PI-2, PI-3 and PI-4. PI-1 to PI-4 were measured for physical properties, and the results thereof are shown in Table 29.

Example 11

<Production of Polyester>

Two drops of titanium triisopropoxide were added to a mixture of Compound (1-1-2) (3.12 g, 2.25 mmol) and butanediol (0.40 g, 4.44 mmol) under nitrogen atmosphere, and the solution was heated and stirred at 220° C. for one hour. After cooling, the content was taken out to obtain 1.91 g of a polyester.

Example 12

A part of the polyester obtained in Example 11 was completely dissolved in NMP (9 g), and this solution was diluted to a suitable concentration by butyl cellosolve and coated on a glass substrate by means of a spinner. It was pre-dried at 80° C. for about 5 minutes and then subjected to heat treatment at 100° C. for one hour and then at 220° C. for 3 hours to obtain a polyester thin film PE-1.

Example 13

The polyester (0.26 g) obtained in Example 11 was pressed by means of a pressing machine (upper face, lower face temperature: 260° C., press pressure: 19.6 MPa) to obtain a polyester substrate having an average thickness of 244 μm.

Comparative Example 2

<Production 1 of Epoxy Resin>

Bisphenol A glycidyl ether (brand name: EPICLON 850S, manufactured by Dainippon Ink & Chemicals Inc.) (0.3 g) and 4,4′-diaminodiphenyl ether (0.176 g) were dissolved in NMP (1.11 g) to obtain an epoxy compound solution having a compound concentration of 30% by weight. This solution was coated on a copper foil, pre-baked at 80° C. for about 30 minutes and then subjected to heat treatment at 220° C. for 60 minutes and then at 220° C. for 60 minutes under reduced pressure, and it was subjected to etching treatment to obtain an epoxy resin film having a thickness of about 40 μm. The above film had an average light transmittance of 65.2% in 400 to 800 nm, and a wavelength in which the light transmittance was less than 1% was 345 nm.

Example 14

<Production 2 of Epoxy Resin>

An epoxy compound solution having a compound concentration of 30% by weight was obtained in the same manner as in Comparative Example 2, except that EPICLON 850S was changed to Compound (1-1-5) (1.0 g) and a use amount of 4,4′-diaminodiphenyl ether was changed to 0.145 g and that a use amount of NMP was changed to 2.67 g. The above solution was treated in the same manner as in Comparative Example 2 to obtain an epoxy resin film having a thickness of about 100 μm. This film had an average light transmittance of 81.4% in 400 to 800 nm, and a wavelength in which the light transmittance was less than 1% was 260 nm. That is, it is apparent that a PSQ skeleton can be introduced into the epoxy resin without adding polysiloxane and that the resulting coating film is improved in transparency as compared with the coating film prepared in Comparative Example 2.
